Description

201126981 VI. Description of the Invention: [Technical Field] The present invention relates to a user equipment, a base station, a communication control method, and a radio communication system. [Prior Art] In the Advanced Long Term Evolution (LTE-A), which is a third generation partnership project (3GPP) Chinese communication standard, a technique called carrier aggregation (CA) has been studied. Carrier aggregation, for example, by forming a communication channel between a user equipment (UE) and a base station (BS, or evolved Node B (eNB)) by aggregating a plurality of frequency bands supported in LTE and improving thereby Communication flux technology. Each of the communication channels included in a communication channel formed by carrier aggregation is referred to as a component carrier (cc). The bandwidths available for the band in LTE are Μ MHz, 3.0 MHz, 5 〇 Hz, 1 〇 megahertz, megahertz and 20 megahertz. Therefore, if five 2 megahertz bands are aggregated into component carriers, a total of One communication channel of 100 megahertz. The component carriers included in one communication channel in the carrier aggregation do not have to be continuous with each other in the frequency domain. The mode in which the medium-and-a-half carrier is configured to be continuous in the frequency domain is called a Continuous mode. The other party & is the aspect in which the component carriers are configured not to be continuous with each other, which is called a discontinuous mode. Furthermore, in carrier aggregation, the number of component carriers in a link is - The number of component carriers in the downlink is not the number of component carriers in the link, etc., and the mode in which the upper and middle views are equal is called the number of component carriers in the number of component carriers in the symmetric mode and the _ plane 'The number of component carriers in the uplink is U9953.doc -4- 201126981 The mode of unequal is called an asymmetric mode. For example, an uplink link t uses two component carriers on a downlink. Middle In the case of three component carriers, it may be referred to as asymmetric carrier aggregation. Further, in LTE, any of frequency division duplex (fdd) and time division duplex (tdd) may be used as a multiplex operation. Since the direction of one of the component carriers (uplink or downlink) in FDD does not change in time, FDD is more suitable for carrier aggregation than TDD. At the same time, as a method for achieving cellular One of the basic technologies of the mobility of one of the communication standards is one of the important topics in the system lte_a. In LTE, a user equipment is measured and connected to a service base station (a current connection) The communication quality of the base station and the communication quality with the surrounding base station and transmit a measurement report containing the measured value to the service base station. After receiving the test report, the service base station is based on the report. The measured values determine whether a handover should be performed. Then, if it is determined that a handover should be performed, according to a prescribed procedure (for example, Patent Document 1 below) at a source base station (a service before handover) base ), the user equipment and a target base station (a service base station after handover) perform a handover 0 [citation list] [patent literature] [patent document 1] No. 2009-232293 Published Patent Application Publication [Draft] [Technical Problem] 149953.doc 201126981 = 'No report has been reported on how to actively perform a handover procedure in carrier aggregation radio communication. For example, as explained above - One of the measurement reports in the typical handover procedure may contain the measurement results of the communication channel with the - service base station and the communication channel with the neighboring base station. However, 'in the case of carrier aggregation... line communication' The time cost required for processing is increased based on the quality level of all component carriers of the communication channels or the transmission of a measurement report. In addition, there is concern that resource efficiency will decrease as the amount of data increases. Therefore, the processing efficiency of the transmission from the start of the self-measurement to the transmission of a measurement report is a problem. At the same time, whether the determination of one of the executions based on a measurement report should be performed affects the quality of service of a radio communication service. Therefore, it is desirable to enhance the efficiency of the processing described above in connection with a measurement report while minimizing the degradation of service quality. In view of the above, it is desirable to provide a novel and improved user equipment, base station, and communication control method that can efficiently perform processing related to a measurement report in accordance with one of the radio communications involved in carrier aggregation. And radio communication systems. [Method for Solving the Problem] According to an embodiment of the present invention, an information processing device (e.g., a base station) is configured to communicate with another information processing device and includes a receiver configured to receive Quality information about the quality of service of the information to be transmitted. An allocation unit is included to determine how to distribute the data to the component carrier based on the quality information. In addition, a notification unit is notified to another information processing device via the inclusion and 149953.doc 201126981 configuration to distribute the allocation information on how the specified data is distributed on the component carrier. The distribution unit can distribute the data differently according to one of the quality information associated with one of the data classifications. The allocation unit is configured to mix data having different quality of service criteria on a common communication channel using carrier aggregation of component carriers. The device maps the component carrier to a quality of service classification set by the allocation unit, the mapping enabling another information processing unit from the time of starting the channel quality measurement to providing a measurement report to the information processing device (eg Dynamic control at a UE). A processor can be included, based on whether the measurement report indicates a better channel quality, and whether a peripheral information processing device is available to another information processing device to determine whether to perform a handover for the another information processing device, which is better Channel quality is better relative to a predetermined threshold. The predetermined threshold may vary for each component carrier in the component carrier. The allocation unit may be configured to depend on the change in channel quality among the component carriers and the (source) availability of the (IV) component carrier. A mapping pattern is selected for assigning data to component carriers. . The "Hai knife with a single channel" determines the change in channel quality among the component carriers via one of the previous channel-quality reports provided by another information processing device. * The knife unit determines the change in channel quality among the component carriers by requesting an auxiliary channel quality report from another poor processing device. 149953.doc 201126981 according to another embodiment for communicating with another information processing device. An information processing device uses a plurality of component carriers and includes a receiver configured to receive how the component will be in the component. The allocation information of the data to be transmitted is allocated among the carriers. The apparatus also includes a control unit configured to perform a process for performing a handover procedure based on the assignment information, wherein the process can transmit a channel quality report or measurement report or determine one of the two measurement start times One or more of them. The allocation information contains information on how to assign data to component carriers based on quality of service guidelines. This material can be categorized into one of a plurality of service quality categories. The control unit is configured to transmit the measurement data to another information processing device when the control unit determines that the channel quality is higher than the channel quality from another information processing device. The control unit is configured to determine that the channel quality is higher based on comparison to one of a predetermined threshold or a greater number of measurements. The Home Control Menu is also configured to determine the channel quality for a plurality of component carriers. The control unit is also configured to begin by determining one of the measurements based on whether the channel quality satisfies a predetermined criterion and comparing one of the resource blocks to a reference value by another information processing device. When the f-level of the respective f-source block of M t H 降至 falls below the corresponding predetermined value, the control unit starts the measurement. The control unit initiates the transmission of the measurement and measurement information based on a program that varies depending on the mapping between the component carrier and the corresponding quality of service for each data classification. 149953.doc 201126981 According to another embodiment, communication between an information processing device and another processing device is performed in accordance with a method and includes quality information of the quality of service.竽方车—(4) Where 拍 Shooting the deficiencies The child method also helps a processor to determine how to match the data according to the quality information; Then, how will the data be distributed to the component processing device. The allocation information on the wave is notified to another resource. According to another embodiment, the communication between an information processing device and another poor processing device is controlled by using the following steps: in the information processing device The receiving designation specifies how the distribution information of the Beko to be transmitted among the subcarriers in the sub 7 is allocated; and a handover procedure is controlled according to the Shai allocation information by a processing person. [Advantageous Effects of the Invention] As explained above, the user equipment, the base station, the communication control method, and the radio communication system according to the embodiments of the present invention can be efficiently executed in accordance with the requirements in the radio communication involving carrier aggregation. Processing related to a measurement report. [Embodiment] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be noted that in the specification and the drawings, structural elements that have substantially the same function and structure are designated by the same reference numerals, and the repeated explanation of the structural elements is omitted.

Background technology > (1 · 1. Handover procedure) And Figure 2 illustrates the technology associated with the present invention. Figure (4) Two processes, one step of carrier aggregation, one of the procedures of lTE in radio communication, as an example of a typical handover procedure. In this example, the handover procedure involves a user equipment (UE), a source base station (original eNB), a target base station (target cnb), and a mobility management entity (MME) 〇 149953.doc • 10 - 201126981 As a preliminary step for one handover, the user equipment first reports the channel quality of a communication channel between the user 3 and the source base station to the source base station (step S2). Channel quality can be reported on a regular basis or when the channel quality falls below the special reference value. The user equipment can measure the channel quality of the communication channel with the source base station by receiving a reference signal contained in the downlink channel from the source base station. Then, the source base station determines the necessity of the measurement based on the quality report received from the user equipment, and if the measurement is required, assigns a measurement gap to the user equipment (step S4). Then, the user equipment searches for the downlink channel (i.e., performs cell search) from the base station during the period in which the measurement gap is allocated (step S12). Note that the user equipment can identify a surrounding base station to search based on a list provided in advance from the source base station. When the user equipment acquires synchronization with the downlink channel, the user equipment performs by using one of the reference signals included in the downlink channel.

Measurement (step S14). During this period, the source base station limits the allocation of data communication related to the use of the T device to prevent the user from setting the transmission of the data. After the measurement is completed, the user equipment will contain one of the results of the measurement. The measurement report is sent to the source base station (step S22). The result of the measurement contained in the measurement report may be an average value of the measurement values of the plurality of measurements and the like. Furthermore, the results of the measurements may contain information about a plurality of frequency bands. After receiving the measurement report, the source base station determines whether a handover should be performed based on the content of the measurement report. For example, it can be determined that in the case of another 149953.doc „ ^ 201126981 a channel quality of the base station is higher than the channel quality of the source base station by a certain threshold or greater, a handover is required. In this case, The source base station determines to perform a handover procedure with one of the associated another base stations (as a target base station), and transmits a handover request to the target base station (step S24). After receiving the handover request, the target The base station determines whether the user equipment is acceptable based on the availability of one of the communication services provided by itself, etc. When the user equipment is acceptable, the target base station transmits a handover request confirmation to the source base station (step S26). After receiving the handover request confirmation, the source base station sends a handover command to the user equipment (step S28). Then, the user equipment acquires synchronization with the downlink channel of the target base station (step S32). The user equipment performs random access to the target base station by using a random access channel in a given time slot (step S34). During this period, the source base station The data addressed to the user equipment is forwarded to the target base station (step S36). Then, after the random access is successfully performed, the user equipment transmits a handover completion to the target base station (step S42). After the handover is completed, the target base station requests the MME to perform routing update of the user equipment (step S44). After the MME updates the route of the user data, the user equipment becomes able to pass through a new base station (ie, the target) The base station communicates with another device. Then, the target base station transmits an acknowledgement to the user equipment (step S46). The series of handover procedures ends thereby. (1-2. Structure of communication resources) FIG. 2 shows LTE One of the communication resources is shown as an example of one of the structures of one of the communication resources applicable to the present invention 149953.doc • 12-201126981. Referring to FIG. 2A, the communication resources in LTE are segmented in time to each having A number of radio frames of one length of 10 msec. One radio frame contains ten sub-frames, and - one sub-frame consists of two 0.5 mn time slots. In the coffee, the sub-frame A unit that allocates a communication resource to each user equipment in the time direction. This unit is called a resource block. The resource blocks contain eleven subcarriers along the frequency direction. Specifically, A resource block has one of 1 mseexl2 subcarriers in the time-frequency domain. The flux of data communication increases with the allocation of a larger number of resource blocks for data communication with the same_width and time length. In addition, in a structure of a communication resource, the 'radio frame has—the portion of the (four) band remains as a random access channel. The random access channel can be used, for example, by having changed from an idle mode. To-active mode - user equipment to - base station - access or in the - handover procedure to - target base station - initial access. <2. Outline of Radio Communication System> (2-1. Overview of System) Fig. 3 is a schematic diagram showing the summer of the radio communication system according to an embodiment of the present invention. Referring to Figure 3, the radio communication system includes a user equipment 100, a base station 20, and a base station 2B. It is assumed that the base station 200a is a service base station of one of the user equipments 100. The user equipment 100 is located within a cell 202a in which one of the radio communication services is provided by the base station 2 & The user equipment 1 can perform one of the other component devices (not shown) on the communication channel by a plurality of component carriers (i.e., by the carrier aggregation) via the base station 149953. Doc 201126981 data communication. However, since the distance between the user equipment 100 and the base station 200a is not short, there is a possibility that a handover is required for the user equipment 1. In addition, the user equipment 100 is positioned at The base station 200b provides a radio communication service in one of the cells 202b. Therefore, the base station 200b can be used as a candidate for a target base station that is handed over by the user equipment 1. The base station 200a can pass through A backhaul link (e.g., interface 2) communicates with base station 200b. For example, 'transfer can be transmitted and received between base station 2& and base station 2〇〇b as explained with reference to FIG. Various messages in the program, scheduling information related to user equipment belonging to each cell, etc. In addition, 'base station 200a and base station 200b can pass through, for example, -S1 interface and _ upper node (for example, a service) Channel (S_GW) or MME communication. It should be noted that when the base station 200a and the base station 20 are not particularly required to be distinguished from the following description in the specification, the letters at the end of the reference symbol are collectively referred to as - Base station fan. This also applies to other components. (2-2. Classification according to Q〇s requirements) In radio communication systems, the quality of service dependent on the service (required -Q°S requirements) Each of the data signals transmitted on the communication channel set forth above is classified into two or more categories—the two & two or more categories that depend on the Q〇S requirement. #(9) The four categories shown in Table 1 (hereinafter referred to as (10) category in the table] are for each of the four Q〇S categories. ^ 〇^ , cheek (1) each has a category name, year one QoS requirements related to one of the genus, the social eve a ', is a consistent example of I · life and a case of a corresponding service. 焉 149953.doc 201126981 [Table i]

Table 1. Classification of your category name Attributes of QoS requirements instance of service instance session error rate transmission delay guarantee bit rate VoIP video conferencing stream error rate transmission delay guarantee bit rate real-time video distribution interaction error rate Web access Database Retrieval Background Error Rate Email The first QoS category is a "session" category. For the "session" category of traffic, three attributes, such as an error rate, a transmission delay, and a guaranteed bit rate, can be defined as the QoS requirements to be met. The error rate can be represented by a Service Data Unit (SDU) error ratio or a residual bit error ratio. The SDU error is greater than the ratio of the SDU to the transmitted SDU from which an error was detected. In addition, the residual bit error ratio indicates the ratio of the bit that is not detected at the end of the reception to the transmitted data bit. This transmission delay indicates the length of delay allowed during transmission. Furthermore, the guaranteed bit rate indicates that one bit rate for a user equipment is guaranteed by the radio communication system 1. Note that the guaranteed bit rate can be replaced with the maximum bit rate (or the maximum bit rate can be used in addition to the guaranteed bit rate). As understood from Table 1, for the traffic belonging to the "session" category, the radio communication system 1 schedules a communication resource in such a manner that the error rate, the transmission delay, and the guaranteed bit rate do not fall below a certain reference value. Corresponding to the category of "I will be 149953.doc -15- 201126981" - the service is - IP phone (read), video conferencing, etc. The second QoS category is a "traffic service, and the error rate can also be determined. The reference value for the QoS requirement to be satisfied may be in the same category as the third QoS category of one of the "session" class flow classes. There are three attribute boundaries for the transmission delay and guaranteed bit rate of the "streaming" category. However, QoS requirements are different for their reference values for these attributes. Corresponds to the "string instance is real-time video distribution, etc. interaction" category. For the "interactive" category of services, only one instance of the service that corresponds to one of the "interaction" categories is web access, database search, etc. The fourth Qos category - "background" category For the "background" category of traffic, you can only define, for example, the error rate as one of the requirements to be met. However, one of the error rate reference values can be different from the reference value of the "interaction" category. One of the services of the "Background" category is an email, Short Message Service (SMS), etc. It should be noted that the classification of the Q〇s categories shown in Table 1 is only an example. For example, another Q〇S Categories may be defined for controlling the transmission of information, such as information officer haircuts (IMS). Regarding the Q〇s category used to control the transmission, one may apply a stricter one of the Q〇S categories described above (or High priority) QoS requirements. Each data signal should be classified into these Q〇s categories.

The QoS class (for example) is determined by an alternate service application and is indicated in one of the headers of the data packet. Fig. 4 is an explanatory diagram for explaining an exemplary structure of a data packet which can be transmitted in the radio communication system 1 149953.doc -16·201126981. Referring to Figure 4, three data packets 4a, 4b and 4c are shown. The billet package 4a is composed of a header section and a data section. The data section of the data block 43 contains the data bits belonging to the -category Ci. The category Ci can be any of Cl = "Meet Lord "When ^» w", C2 = Streaming, C3 = "Interaction" and C4 = "Back". Therefore, in this case, the data packet 4a contains only one packet belonging to one of the data signals of a single category. The data section of the beaker package 4b contains the information bits belonging to the category Ci and a category Cj. The category Cj can also be any of C1 = "session", C2 = "_stream", C3 = interaction" and C4 ~ "background" (however, it is different from category Ci). In this way, data bits of different Q〇s categories can be combined in one data packet. The data packet is distributed to a plurality of data packets of a multiple input multiple output (MIM) stream. One of the first data streams contains data bits belonging to category ci. One of the data streams of the second ΜΙΜ0 stream contains data bits belonging to the category Cj. In this way, data bits belonging to different Q〇s categories can be contained in individual data packets distributed to a plurality of MIM〇_streams. In this embodiment, the radio communication system 1 is configured to be mixable therein. Processing relating to one of the radio communications in one of the carrier aggregations is effectively performed in an environment of data signals belonging to a plurality of QoS classes. (2-3. Channel quality report and measurement report) The channel quality report is sent from the user equipment to the service base station.

I 149953.doc -17· 201126981 Notice. Based on the channel quality report, the serving base station performs link adaptation (including, for example, rate control, power control, etc.) to a communication channel of the user equipment. As previously explained with reference to Figure 1, the user equipment measures the channel quality of the communication channel by receiving a reference signal contained in the downlink channel from the serving base station and then transmits the channel quality report to the serving base station. The measurement of the channel quality for channel quality reporting is performed with respect to each resource block. Further, in this embodiment, the channel quality measured for each channel block for the channel quality report may be a condition for starting the measurement of a handover (one condition for triggering measurement). The measurement report is also sent from the user equipment to one of the service base stations. Based on the measurement report, the service base station determines whether a delivery should be performed. The measurement of the channel quality for the measurement report is typically performed with respect to each communication channel between the serving base station or a surrounding base station and the user equipment as previously explained with reference to FIG. In this embodiment, the other side's measurement is performed with respect to each component carrier since each communication channel is composed of a plurality of component carriers. Furthermore, in this embodiment, data signals belonging to a plurality of QoS classes can be mixed in one communication channel. Therefore, by configuring the user equipment and the base station (and an upper node) elaborated in the following sections, the self-measurement can be dynamically controlled according to a mapping between a component carrier and a Q 〇S class. Start processing to the transmission of a measurement report. <3. Exemplary Configuration of Device According to Embodiment> (3-1 - Example Configuration of User Equipment) FIG. 5 shows one of configuration of user equipment 1 according to an embodiment 149953.doc •18- 201126981 A block diagram of the example. Referring to FIG. 5, the user equipment 1 includes a radio communication unit 110, a signal processing unit 15A, a controller 16A, and a measurement unit 170. (Radio Communication Unit) The radio communication unit 11 performs radio communication with one of the base stations 2 on one of communication channels formed by aggregating a plurality of component carriers using a carrier aggregation technique. Figure 6 is a block diagram showing one example of a more detailed configuration of one of the radio communication units 110. Referring to FIG. 6, the radio communication unit 丨丨〇 includes an antenna 112'-switch Π4, a low noise amplifier (LNA) 12(), a plurality of down converters 122a to 122c, a plurality of filters 124& to 124c, A plurality of analog-to-number converters (ADCs) 126a to 126c' - a demodulation unit 128, a modulation unit 130, a plurality of digits to an analog converter 132c, a plurality of filters 1343 to n4c, and a plurality of up-converters Up to 136c, a combiner 138 and a power amplifier (pa) 14 〇. The antenna 112 receives a radio signal transmitted from the base station 2 and outputs the received signal to [1^12] through the switch 114. The LNA 12〇 amplifies the received signal. The down converters 122 & and filter 124a separate one of the first component carrier (CC1) baseband signals from the received signal amplified by the LNA 12A. The baseband signal after the knife is converted by the ADC 126a into a digital signal and output to the demodulation unit 128. Similarly, the down converter 122b and the filter 124b separate the received signal, which is one of the first baseband signals (CC2), freely 12 〇 amplified. The separated baseband signal is then converted by adc 126b into a digital signal and output to demodulation unit 128. In addition,

S 149953.doc -19·201126981 The down converter 122c and the filter 124c separate the received signal from which the baseband signal of one of the third component carriers (CC3) is amplified by the LNA 120. The separated baseband signal is then converted by the ADC 126c into a digital signal and output to the demodulation unit 128. Thereafter, the demodulation unit 128 generates a data signal by demodulating the baseband signal of the respective component carrier and outputs the data signal to the signal processing unit 150. Further, when a data signal is input from the signal processing unit 150, the modulation unit 130 modulates the data signal and generates a baseband signal of each component carrier. Among the baseband signals, the baseband signal of the first component carrier (CC1) is converted into an analog signal by the DAC 132a. Then, by the filter 134a and the up-converter 13 6a, the analog signal is generated corresponding to a transmission signal.

A frequency component of the first component carrier in the number. Similarly, the baseband signal of the second component carrier (CC2) is converted to an analog signal by the DAC 132b. A frequency component corresponding to the second component carrier in the transmitted signal is then generated from the analog signal by filter 134b and upconverter i36b. In addition, the baseband signal of the third component carrier (CC3) is converted to an analog signal by the DAC 132c. Then, a frequency component corresponding to the third component carrier in the transmission signal is generated from the analog signal by the filter 丨 34c and the up-converter 136c. After the combination by the combiner 138 corresponds to the three

The frequency components generated by the binary carriers are formed, and the transmission signal is formed. The pA 140 amplifies the transmission signal and outputs the transmission signal to the antenna 112 through the switch 114. Antenna 112 then transmits the transmitted signal to base station 200 as a radio signal. Although the case where the radio communication unit 11 〇 handles three components 149953.doc • 20 - 201126981 carrier is illustrated in FIG. 6 , the number of component carriers handled by the radio communication unit 110 may be two or four or more. . Further, instead of processing the signals of the respective component carriers in the analog region (as in the example of Fig. 6), the radio communication unit 11 can process the signals of the respective component carriers in the digital region. In the latter case, at the time of reception, a digital signal converted by one ADC is separated into signals of respective component carriers by a digital filter. In addition, during transmission, after frequency conversion and combining the digits h of the carriers in the respective knives, the signal is converted by a DAC into a class k and the load of the DAC is when the signals of the respective component carriers are processed in the analog region - It is small. On the other hand, when the signals of the respective tool carriers are processed in the digital area, one of the sampling frequency of the AD/DA conversion is relatively large, and the load of the ADC and the DAC can be increased by this. (Signal Processing Unit) Referring back to Fig. 5, an example of one of the configurations of the user equipment 1 is explained below. The signal processing unit 150 performs signal processing, such as deinterleaving, decoding or error correction, on the demodulated data signal input from the radio communication unit. The 'signal processing unit 15' then outputs the processed data signal to an upper layer. Further, the signal processing unit 15() performs signal processing on the data signal input from the upper layer, for example, encoding or interleaving 1, and the signal processing unit is rotated to the radio communication unit (10) via the processed data signal. (Controller) The controller (10) controls the overall function of the user equipment by using a processing device (for example, a central processing unit (CPU) or a digital signal processor (Sec)) 149953.doc • 21 · 201126981. For example, the controller 160 controls the timing of the data communication based on the schedule information received from the base station fan by the radio communication unit 11G by the radio communication unit j. In addition, the controller 16 controls the measurement unit 170 to measure the channel quality of each resource block by using the reference signal from the base station 20 (the system-service base station), and transmits the channel quality through the radio communication unit 110. Send a channel quality report to the base station 2〇〇. Further, the controller 160 receives, via the radio communication unit 11, a control information relating to a mapping between each of the component carriers and the Q〇s class of each data signal from the base station 200. The control information may be the same or different information as the scheduling information described above. Then, the controller 160 controls at least one of the measurement of the quality of the channel and the transmission of the measurement report by the measurement unit 17 in accordance with a program that varies depending on the control information. The processing related to the measurement report will be explained in further detail later. (Measurement Unit) The test order 7L 170 measures the channel of each resource block in a component carrier by, for example, using a reference signal from the base station 2 according to control from the controller i 6 〇 quality. In addition, the measurement unit 17 performs a handover measurement with respect to each of the component carriers in accordance with control from the controller 16A. The result of the measurement performed by the measuring unit 17() is converted by the controller 160 into a specific format for a measurement report and transmitted to the base station 200 via the radio communication unit 110. Thereafter, based on the measurement report, & platform 200 determines whether a handover should be performed for user device 100. It is noted that the controller 160 can cause the measurement unit 17 to start measuring at regular intervals, and in this embodiment, the controller i 6 can be borrowed in each of the 149953.doc • 22· 201126981 resource blocks. When the measurement unit i 70 measures the channel quality for the channel quality report and does not satisfy a specific reference, the measurement unit 170 starts measuring. In either case, controller 1 60 may generate an amount when, for example, the channel quality of another base station in one of the measurement results is higher than the channel quality of the serving base station by a certain threshold or greater. The report is sent and sent to the base station 200. Herein, a threshold (or reference value) that varies, for example, for each component carrier can be used. Note that, as explained later, one of the reference values to be used may be specified by the base station 2, depending on the conditions under which the measurement should be started (i.e., on a rule basis, according to a specific criterion, etc.). (3-2. Example Configuration of Base Station) Fig. 7A is a block diagram showing an example of one configuration of the base station 2 according to the embodiment. Referring to FIG. 7A, the base station 200 includes a radio communication unit 210, an interface unit 250, a storage unit 260, a controller 270, and a QoS manager 280. (Radio Communication Unit) One of the specific configurations of the radio communication unit 21 can be similar to the configuration previously described with reference to FIG. 6 of the radio communication unit 11 of the user equipment 1, although the number of component carriers to be supported, processing One of the requirements for performance is different. The radio communication unit 210 performs radio communication with one of the user equipments on one of the communication channels formed by aggregating a plurality of component carriers using a carrier aggregation technique. (Interface Unit) Interface unit 250 is interposed between, for example, the "Interface Mediation Radio Communications Unit 210, Controller 270 or Q〇S Manager 280 and an Upper 149953.doc • 23-201126981 node illustrated in FIG. In addition, the interface unit 25 transmits, for example, the X2 interface illustrated in FIG. 3 as a medium causing communication between the radio communication unit 21, the controller 270, or the QoS manager 280 and another base station. The storage unit 260 maintains an indication with respect to each of the user devices belonging to the cell of the base station 2 by using a storage medium (eg, a hard disk, a semiconductor memory, etc.) Which component carrier is being used by the user equipment for communicating CC management data. The controller 27 can be updated by the controller 27 when an additional user equipment joins the cell of the base station 200 or when the existing user equipment changes a component carrier. Therefore, the controller 27 can discriminate which component carrier is being used by the user equipment 1 by referring to the CC management data. Further, the storage unit 260 stores The link characteristic data generated by the controller 270 indicating the characteristics of each link based on the channel quality report transmitted from the user device 1 is further stored. The storage unit 260 stores the indication that each of the messages should be satisfied in each of the messages. QqS data of an attribute value of a QoS class (for example, an error rate, a transmission delay, or a guaranteed bit rate). The link characteristic data and the Q〇S data are used in the scheduling-communication resource to determine the component carrier. A mapping between each of the data signals and the Q〇S class of each data signal. (Controller) The controller 270 controls the overall functionality of the base station by using a processing device (e.g., a CPU or a Dsp). In other words, the controller 27 is scheduled by the user equipment lGG based on the value of the value of each category 149953.doc • 24· 201126981 that should be satisfied in each transaction and notified by the (10) manager coffee. For data transmission, for example, 'the preferred 'controller' for which the strict delay is applied to the transmission delay, the wanted resources are allocated in parallel along the frequency direction as much as possible by the controller 270. One The mapping of communication resources is a mapping between each of the carriers and the QoS classification of each data signal. Three typical patterns of this mapping (six variations) will be further explained later by way of example. In addition, the controller 270 determines whether the handover by the user equipment 1 to another base station should be performed by using the measurement report described above transmitted from the user equipment 1 . The controller 270 transmits, via the radio communication unit 210, control information specified by the schedule related to a mapping between each of the left component and the Q 〇S category of the data signal to the user equipment 1 . In addition, the controller 27 receives, via the radio communication unit 210, a measurement report generated and transmitted by the user equipment 1 according to a program that varies depending on the control information. The controller 27 then determines whether a handover by the user equipment 1 to another base station should be performed by using the received measurement report. (QoS Manager)

The QoS manager 280 typically manages one of the Q s s requirements to be satisfied in each of the services by using, for example, QoS data stored in the storage unit 26A. In addition, the q〇s manager 280 will notify the controller 270 of a Q s request for a profile signal as a schedule-target before scheduling a communication resource. At this time, when there is a possibility that one of the requirements of Q〇s is not satisfied, the q〇s manager 280 negotiates with another base station or an upper node to change a 149953.doc

I -25- 201126981 One of the Radio Access Network (RAN) paths, using a wired link, etc. to meet QoS requirements. Note that the QoS Manager 280 can be placed in one of the upper nodes of the base station 2 instead of being placed in the base station 200. The upper node of the base station 200 corresponds to, for example, a node such as a service gateway, MME, or the like. Figure 7B is a block diagram showing another example of this configuration. In Fig. 7B, the q〇s manager 28, which is shown in the components of the base station 2A in Fig. 7A, is placed in an upper node 3A of the base station 200. Referring to FIG. 7B, the base station 2A includes a radio communication unit 210, an interface unit 250, a storage unit 260, and a controller 270. In addition, the upper node 3A includes a Q〇s manager 28A and a storage unit 360. The storage unit 360 stores, for example, at least QoS data stored in the data in the storage unit 260 set forth above. (3-3. Mapping Between Component Carriers and Categories) A typical mapping between each of the component carriers and the QoS class of each packet 彳i number is explained below with reference to FIGS. 8 to 〇d. Model. (First Model) FIG. 8 is an explanatory diagram illustrating a first type (pattern ρι) of a map between each of the component carriers and the Q 〇 s class of each data signal. The first type may be a type used when one of the data signals to be transmitted contains only data bits belonging to a single QoS class. Referring to Figure 8, a data signal contains data bits belonging to only category c. The controller 270 of the base station 200 is responsive to one of the notifications from the Q〇s manager 28. Q〇S requires that their data bits be evenly or unevenly distributed to the respective component carriers. In the example of Fig. 8, the resource blocks in the component carriers CCl, CC2, and CC3 are unevenly distributed at a ratio of 3:2:1, respectively, 149953.doc -26-201126981. The ratio may be determined depending on, for example, the channel quality or availability of resources for each of the component carriers. (Second Type) FIG. 9 is an explanatory diagram illustrating a second type (pattern p2) of a map between each of the component carriers and the q〇s class of each data signal. The second type of sample may be used in the case where one of the data signals to be transmitted contains a plurality of data bits of the q〇s class. Referring to Figure 9, a data signal contains data bits belonging to categories C1, C2, and C3. The controller 270 of the base station 200 distributes the data bits to the respective component carriers in such a manner that the data bits classified into different classes are transmitted on different component carriers. For example, when the qos requirement for category C is the most stringent (with the highest priority), controller 270 assigns the data bits belonging to category C1 to component carrier CC1 having the highest channel quality. In addition, controller 270 assigns data bits belonging to category C2 whose Q〇s requirement is the second most stringent (having the second highest priority) to component carrier CC2 having the second highest channel quality. In addition, controller 270 assigns the data bits belonging to category C3 whose Q〇s requirement is the least stringent to having the remaining component carrier CC3. In the second type, since one of the data belonging to one of the Q〇s categories is transmitted only in one component carrier, one of the costs of the management of q〇s is reduced. (Third Type) Figs. 10A to 10D are explanatory diagrams illustrating a third type of one of a map between each of the component carriers and the Q 〇 S category of each data signal. similar

S 149953.doc -27- 201126981; The f4 second type can be used in the case where the data signal to be transmitted contains a plurality of data bits of the Q〇S category. However, in the third type of φ, 1, the data bits classified into different categories from each other can be distributed to a single branch _ knife carrier. That is, according to this pattern, data bits belonging to different types of data can be shared - a single component carrier. In the following, four variations of the third type (i.e., patterns P3a to P3d) are sequentially described. Referring to Fig. 10A (type p3a), a data signal contains data bits π belonging to the categories, c2 and C3. The controllers of the base station 2〇 distribute their data bits 7L to the respective component carriers at the same rate. Specifically, the ratio of the data bits belonging to the class C1, C2, and C3 to the component carrier CC1 is the same as the corresponding ratio in the component carriers CC2 and CC3. In the pattern p3a, since the distribution of the data bits is determined by the common ratio, the mapping is simplified and the processing cost for one of the schedules can be reduced. Moreover, by the effect of interleaving, it is expected that better link characteristics are obtained than when only data bits belonging to the same type are distributed to the same component carrier. Referring to Fig. 10B (model P3b), a data signal contains data bits belonging to categories C1, C2, and C3. Controllers 270 of base station 200 distribute their data bits to respective component carriers at a different rate. In the example of Figure B, the data bits belonging to categories C1, C2 and C3 are distributed to the component carrier cc i . On the other hand, the data bits belonging to category C1 are only distributed to component carrier CC2. In addition, the data bits belonging to categories C2 and C3, respectively, are only distributed to component carrier CC3. In the pattern P3b, since the amount of communication resources allocated to each component carrier can be increased or decreased depending on the stringency (priority level) of a Q〇s requirement, a more flexible schedule can be performed to satisfy the Q〇s 149953.doc • 28- 201126981 Requirements. Referring to Fig. 10C (model P3c), a data signal contains data bits belonging to categories C1, C2, and c3. Controller 270 of base station 200 distributes their data bits to a component carrier. The pattern P3c can be used when the channel quality of one component carrier is significantly higher than the channel quality of other component carriers and there is sufficient available resources. Referring to Fig. 10D (type P3d), a data signal contains data bits belonging to categories q, C2, and C3. The controllers 270 of the base station 200 distribute their data bits to respective component carriers at a different rate. Further, unlike the type shown in Fig. 10B! > 31?' In the pattern p3d, the controller 27 distributes the data bits belonging to different classes to one resource block. In the example of Fig. i〇d, the data bits belonging to the categories C1, C2 & C3, respectively, are distributed to the component carrier CC2. Then, the data bits belonging to the category (^ and ^ are distributed to the component carrier CC2 - the resource block RB. In addition, the data bits belonging to the categories C1 and C3 are distributed to the component carrier ^ (4). In the type (4) In the process, the resource block can still be used as a single=two flexible schedule. (Selection of mapping type) When scheduling a communication resource, the controller 27 can depend on the channel quality change in the component carrier or The availability of the resources of the individual component carriers to select which one of the above-mentioned types should be used. Table 2 below shows the example of one of the (4) types of selection criteria. Note that the following mainly describes the poor ones to be transmitted. The material signal contains the data bits belonging to a plurality of Q〇s categories. § 149953.doc 201126981 [Table 2] Table 2. Examples of selection criteria for mapping patterns Resource availability quality changes All CCs meet certain criteria Certain CC does not meet certain criteria. All CCs satisfy Case 1-1. Case 1-2 Specific criteria (single category - P1) Type P3d Multiple categories - Type P2 or P3a Some CCs do not satisfy Case 2. 1 Case 2-2 Specific criteria Type P3b Pattern P3c In Table 2, the availability of a resource can be assessed based on, for example, one of the component carriers, and can be based on, for example, a component carrier obtained through a channel quality report. The channel quality of each is used to assess the change in quality. For example, as the availability of resources, it is assumed that the usage rate is lower than a specific reference for all component carriers (ie, there are enough available resources). When the component quality is higher than a specific reference for the component carrier, the controller 270 may select the pattern Ρ 2 or the pattern P3a (case 1-1). In the case where it is desirable to reduce the cost required for QoS management, Pattern P2 is selected. On the other hand, in the case where it is desired to improve the link characteristics, the pattern P3 can be selected. Further, when the resource availability is the same as the resource availability of the case 1-1 and the channel quality is not satisfied When a particular reference to one of the component carriers, the controller 270 may select the pattern P3d (case 1-2). Furthermore, when (such as the availability of resources) there is its use for all component carriers When the rate is higher than a specific reference (that is, there is not enough available resources) 149953.doc -30· 201126981 one component carrier and the channel quality is higher than a specific reference, the controller 2 can select the pattern P3b (in addition, When the source availability is the same as the resource availability of the situation and there is a component carrier whose channel quality does not satisfy a specific reference, the controller 270 may select the pattern P3c (Case 2_2, the controller 270 of the base station 200 by using this one The selection criteria are used as an instance to determine a mapping between each of the component carriers and the Q〇s category of each data signal. Then, the controller 27 transmits the control information related to the mapping to the user equipment through the radio communication unit 21, and the control information related to the mapping can be controlled by, for example, one of the downlinks. Schedule information delivered by a channel or a broadcast channel. Preferably, the control information associated with the mapping indicates a mapping between one of the resource blocks in each of the component carriers and the q s s category of each of the data signals transmitted in the resource block. Further, the control information associated with the mapping may contain an identification code for identifying the mapping pattern employed. Thereafter, as explained above, the controller 160 of the user device 100 performs the measurement based on a program that varies depending on the control information transmitted from the base station 200 and transmits a measurement report to the base station 200. In the following sections, one of the processes of one of these types of mappings is elaborated. <4. Flow of Process According to Embodiment> Fig. 11 is a sequence diagram showing an example of one of the flows of one of the communication control processes in the radio communication system 1 according to the embodiment. Referring to Fig. 11, as an example, a communication control process is displayed along three routes corresponding to the user equipment 100 and the controller 270 and the QoS manager 280 of the base station (eNB) 200, respectively. 149953.doc • 31- 201126981 (4-1. Exchange of QoS Information) First, before the controller 270 schedules a communication resource, the controller 270 exchanges with the QoS manager 280 with a Q〇S request. Information about (step S102). For example, when a "session" category or a "streaming" category of traffic exists, the QoS manager 280 notifies the controller 270 of the value of the (allowable) transmission delay for each category. In addition, the QoS manager 280 notifies the controller 270 of an index value of an error rate (e.g., an SDU error ratio or a one-bit error ratio). Alternatively, the 'q〇s manager 280 can notify a controller 270' of a guaranteed bit rate and the controller 270 can calculate an index value to satisfy one of the error rates based on the guaranteed bit rate. In response to this, the notification controller 270 replies to the QoS manager 280 as to whether a communication resource can be scheduled to meet the q〇s requirement. When it is difficult to make the schedule meet the Q〇s requirement, the QoS manager 280 can negotiate with another base station or an upper node for one of the RAN's paths, a wired link utilization, and the like. Alternatively, QoS manager 280 can determine that traffic having a relatively low priority class (e.g., "interactive" category or "background" category) is not transmitted until later. (4-2. Determination of Mapping) Then, the controller 270 determines, based on the QoS requirements notified from the QoS manager 280, each of the component carriers and the QoS class for each of the data signals for the user equipment 1 A mapping between the two, and scheduling a communication resource (step S1 〇 4). The mapping is determined in dependence on the change in channel quality among the component carriers and the resource availability of the respective component carriers as set forth above. In general, the improvement of the channel f among the component carriers can be calculated through a previous 149953.doc • 32. 201126981 channel quality report (step su4 described later) in the repetitive communication control process of the figure. Alternatively, the base station controller may request the user '1GG to determine a map of one of the maps at step S1G4 (separate from step S114). Thereafter, the controller 27 transmits the indication information via the downlink-control channel or a broadcast channel to the user equipment 1 (step si 6). At this step t, the controller 27 can explicitly notify the user device J 识别 of the identification horse that strongly identifies a mapping pattern. In addition, when mixing data signals belonging to a plurality of QoS classes, the controller 27() may additionally notify the index value (e.g., the minimum required signal interference noise ratio (9) nr for each of the QoS classes) or the minimum received power) User device 100 is provided. (4-3. Channel Quality Report) Meanwhile, the user equipment 100 measures by receiving one of the reference signals in each of the resource blocks of each component carrier of the downlink channel from the base station 2 The channel quality of each resource block (step S112). Then, the user device 100 transmits a channel quality report generated by using the measured quality level to the base station 200 (step S114). The content of the channel quality report may vary depending on the mapping pattern that the user equipment 1 knows from the control information obtained from the base station 200 in step S106. The contents of the channel quality report corresponding to each mapping type are described below. (In the first pattern) In the first pattern illustrated in Fig. 8, only one of the data signals belonging to the class of q〇s is mapped to all of the component carriers constituting a communication channel. In this case, the user equipment 100 may only include, for example, the representative values (eg, average, minimum, etc.) of the quality levels of all resource blocks of the 149953.doc • 33- 201126981 wave to the channel. In the quality report. (In the second type) In the second pattern illustrated in Fig. 9, one of the data signals belonging to one of the q〇s types is mapped to each of the individual component carriers constituting a communication channel. In this case, for example, the user equipment 100 may determine, for each of the component carriers, a representative value of the quality level of all resource blocks in each of the component carriers and include their representative values in the channel quality report. in. Alternatively, the user equipment 100 may include only the representative value having the lowest quality level among the representative values of the quality levels of the respective component carriers into the channel quality report. In addition, the user equipment 100 may include, for example, a representative value of the quality level of the component carrier corresponding to one of the highest priority levels (eg, "session" category, stream" category, etc.) to the channel. In the quality report. In addition, the user equipment 100 can be weighted by, for example, a representative value of the quality level of each of the other J-carriers by using the following expression (i) that is dependent on one of the QoS requirements of each QoS class. Summing to calculate a representative value of the entire communication channel. For example, the weight required to depend on one of each Q〇s category Q〇s may be, for example, dependent on an index value from the base station 2 notification (eg, minimum required SINR or minimum received power) A value. [Expression 1] η

QaU = Y^cciQcci 卜 -1 (i) In the expression (1), the 'representative value of the Qan quality level' is calculated as a single value in the entire 149953.doc -34· 201126981 pass k channel. In addition, the number of one component carriers, the number of η-based component carriers, w^ is a weight of each of the 〇〇3 categories corresponding to one of each of the branching carriers, and Qm is a representative value of the quality level of each component carrier. . The single representative value calculated in this way for the quality level in the entire communication channel can also be included in the channel quality report. (In the third type) In the third pattern illustrated in Figs. 10A to 10D, there is a possibility of mapping data signals belonging to a plurality of QoS classes to one single component carrier. In this case, for example, the user equipment may determine, for each of the component carriers, a quality level corresponding to a resource block having a QoS class of one of the priority levels in each component carrier. Represent the values and include their representative values in the channel quality report. Alternatively, the user 6 may further determine, for example, a representative value of the quality level of each of the plurality of component carriers and include the representative values of the respective Q〇S categories to the channel quality report. in. In addition, the user equipment 100 can, for example, rely on the weighted summation of the representative values of the quality levels of the respective QoS classes by using the following expression that is dependent on one of the Q 〇s requirements of each QoS class. Calculate a single representative value for the entire communication channel. As set forth above, the weight dependent on one of the QoS criteria may be, for example, dependent on a value from one of the base station 200 notification values (e.g., minimum required sINR or minimum received power). [Expression 2] 149953.doc 201126981 Q,i>c"Qc』 Household 1 (2) In the expression (2), the representative value of the Qall quality level is calculated in the entire communication channel - a single value. In addition, the number of categories, the number of η categories, the number of weights of each Q〇S category of the VeJ system, and the representative values of the quality levels of each QoS category of Q and j. The quality of the entire communication channel, etc., can also be included in the channel quality report. As explained above, by each of the component carriers and each of the data signals A mapping between the QoS classes dynamically calculates the value of the quality level to be included in the channel. The number of communication resources required for the channel quality report can be reduced. In addition, one of the carrier aggregations is involved. The radio channel can also effectively generate an effective channel quality report. (4-4. Determination of the start of measurement) Then, the controller 270 of the base station 200 allocates a measurement gap to the user equipment 1 (step S116). In addition, the controller 27 notifies the user device 100 of the information to be used for performing the measurement by the user device 100, such as, for example, information indicating which condition should be measured and the desire to start measurement. One of the reference values is used. Thereafter, the user equipment 进行 makes a determination regarding the start of the measurement (step S122). For example, when the notification from the base station 2 is performed on a rule basis At the same time, the user equipment 1 starts the measurement at a regular interval counted by a timer. On the other hand, when the start of the measurement is determined based on whether the channel quality satisfies a special reference, the user equipment 100 will each Resources 149953.doc • 36- 201126981 The measured quality of the block is used to compare the quality level of the channel quality report with the reference value of one of the base two 200 notifications. The specific second test in the latter case; (4) in the mapping pattern And the change - reference. The details of the determination corresponding to the beginning of the measurement of each mapping type are described below. (In the first type) In the first type illustrated in Figure 8, Only one of the data signals belonging to one of the q〇s categories is mapped to all of the component carriers constituting a communication channel (as explained above). In this case, the user equipment 100 can be any of all component carriers. The measurement is started when the quality level of the block becomes lower than a reference 1. In this paper, for example, different reference values from one component carrier to another component carrier can be used. The reference value used herein can be used. Depending on the number of resource blocks allocated to each component carrier, the other is selected as, for example, the representative value of the quality level of the user equipment 1 in any component carrier (each resource block) When the minimum value, the average value, etc. of the quality level becomes lower than a reference value, it is determined to start the measurement. In addition, the user equipment 100 can assign a representative value of the quality level of the component carrier of one of the most communication resources to it. When it becomes lower than a reference value, it is determined to start the measurement. (In the second pattern) In the second pattern illustrated in FIG. 9, one of the data signals belonging to one category is mapped to the constituent one. Each of the component carriers of the communication channel (as set forth above). In this case, for example, the user equipment 1 may range from one component carrier to another depending on the priority level of the corresponding QoS class. Reference values differing from the carrier are used as reference values for the comparison of quality levels 149953.doc -37- 201126981. The user equipment (10) may start, for example, when the representative value of the quality level in the -component carrier having the one of the -high level one of the Q〇S categories becomes lower than the -reference value (and (four) - the criterion of the type) Make measurements. (in the third type) The third type _ U(4) illustrated in Figures 10A to H)D is mapped to one of the component carriers of the plurality of QoS classes (as explained above) ). In this case, for example, the user equipment 100 may change the reference value depending on whether the component carrier has a resource block corresponding to one of the QoS classes having a high priority level. (4) Reference value of the comparison of the quality levels. . The user equipment (10) may start when, for example, the quality level of any resource block corresponding to the __QgS_ having a high priority level becomes lower than the reference value (not the criterion of the first type). Measurement. Alternatively, for example, the user equipment may represent a representative value of the quality level in a plurality of component carriers having a high priority level of one of the Q 〇 S categories (the product of each resource block) When the ## level minimum, average value, etc. becomes lower than a reference value, it is determined to start the measurement. As explained above, the amount can be determined by using a criterion that varies depending on the mapping pattern; then it is necessary to reduce the measurement to ride the appropriate quality of service in one of the radio communications involving carrier aggregation. One of the costs. Flexible control of the program according to the Q〇s requirement is also achieved by using a criterion based on component carrier variation. (4-5. Measurement report) Then, after obtaining the synchronization with one of the downlink channels of one of the neighboring base stations by the cell search, the user equipment 1 is included in the next 149953.d〇c -38- 201126981 One of the reference channel signals is used to perform the measurement (step S丨24). Then, the user equipment 1 transmits a measurement report to the base station 200 based on one of the measurements (step S126). Thereafter, the base station 200 determines whether a handover should be performed based on the content of the measurement report. In addition, the user equipment 1 确定 can determine whether a measurement report should be sent to the base station 200 based on one of the measurements. A determination as to whether a measurement report should be sent may be made based on a criterion that varies depending on a mapping between each of the component carriers and the QoS class of each data #. Details regarding the determination of the transmission corresponding to one of the mapping reports for each of the mapping patterns are set forth below. (in the first pattern) In the first pattern illustrated in Fig. 8, only one of the data belonging to one of the q〇s categories is mapped to all of the component carriers constituting a communication channel (as described above). set forth). In this case, the user equipment 1 may, for example, when the channel quality of another base station in the periphery is higher than the channel quality of the base station 200 by a certain threshold or greater for any component carrier. Make sure to send a measurement report. Any component carrier may be, for example, the component carrier with the highest channel quality of the base station 2 & (i.e., the serving base station). Alternatively, any component carrier may be assigned one of the most resource blocks of the resource block. In addition, different thresholds may be set from one component carrier to another. In this case, the measurement report can be sent when the difference in channel quality for either or both of the component carriers exceeds the respective corresponding threshold. For example, a threshold that varies depending on the number of resource blocks allocated to each component carrier can be set. (in the second type) 149953.doc 201126981 In the second version illustrated in FIG. 9 'maps one of the data signals belonging to one of the Q〇s categories to each of the component carriers constituting a communication channel (as explained above). In this case, the user equipment 100 may, for example, have a channel quality higher than that of the base station 200 for another base station in the vicinity for a component carrier corresponding to one of the QoS classes having a high priority level. A specific threshold or higher (rather than the first type of criteria) determines to send a measurement report. In addition, different thresholds can be set from one component carrier to another. In this case, the measurement report can be sent when the difference in channel quality for any of the component carriers or the owner exceeds the respective corresponding threshold. For example, a threshold value that varies depending on the priority level of the corresponding Q〇s category can be set. (In the third type) In the third pattern illustrated in FIGS. 10A to 10D, there is a possibility of mapping one of the plurality of QoS classes to one component carrier (as explained above) . In this case, the user equipment 100 may, for example, be in the channel quality of another base station in the vicinity for any component carrier having a resource block corresponding to one of the high priority classes q〇s categories. A higher than a certain threshold or higher of the channel quality of the base station 200 (rather than the first type of criteria) determines to send a measurement report. In addition, a threshold value different from one component carrier to another component carrier can be set. In this case, the measurement report can be sent when the difference in channel quality for any of the component carriers or the owner exceeds the respective corresponding threshold. For example, 5 ' may set a lower threshold for one component carrier having a resource block corresponding to one of the high priority levels Q 〇 S category, and for other points 149953.d 〇 c -40 - 201126981 The carrier is set to a higher threshold. As explained above, by determining whether a measurement report should be transmitted by using a criterion that varies depending on the mapping pattern, it is possible to suppress the transmission of communication resources through a measurement report and maintain one of the radio communication involving carrier aggregation. The consumption of appropriate service quality. In addition, the measurement report generation process can be omitted without transmitting a measurement report. Flexibility control of the program according to the Qos requirement is also achieved by using a criterion that varies according to the component carrier. (5.
